I am currently modelling the operation of a wankel engine. As some people have posted in this forum, all difficulties come from the gap between rotor tips and the housing wall. I found some old threads and somebody said that the problem can be done by importing momentum source around the tips. Does anyone know how to carry out this?

Many thanks

You need to creat a new zone in the mesh at the tips.
After this yo will find the source terms at Define/Cell Zone Conditions...
Choose the desired zone and click Source terms and so on.

Thanks for your advice.

I have tried to mark those cell at tips and then seperate them into a new zone. However, in the dymanic mesh, how can I make the new zones move with the tips? The marked cells were unmarked again after I ran the dynamic mesh.
